Description
Technical field
The invention belongs to technical field of composite materials, relate to a kind of high performance resin mortar being applicable to FRPM pipe clamp layer of sand
And preparation method thereof.
Background technology
FRPM pipe is as a kind of long distance water transfer tubing at present, has been obtained for extensively should at China's many water supply and sewage work
With.FRPM pipe has high-strength light, corrosion-resistant, hydraulic characteristic(s) is excellent and the feature such as service life length, according to selecting resin base
The difference of body type, FRPM pipe can also meet the demand of different water supply and sewage work, have good adaptability.
Resin mortar is an up the main material of FRPM pipe stiffness, and pipe stiffness is had very by the bending property of resin mortar
Important impact.At present in FRPM pipe industry, the resin mortar modulus of elasticity in static bending of China's existing technique manufacture is about 6-
8GPa, resin content is about 16%-20%；The resin mortar modulus of elasticity in static bending that overseas enterprise manufactures is about 12.5GPa, resin
Content is reduced to 11.5%.But, even if in the FRPM pipe made by technique leading in the world, its main production cost still collects
In in resin sand pulp layer.Therefore, improving the material property of resin mortar, reducing production cost is current FRPM pipe and relevant tube
The important topic that road industry development is faced.
Summary of the invention
It is an object of the invention to provide a kind of high performance resin mortar being applied to FRPM pipe and preparation method thereof, use
The resin mortar resin demand that the method the manufactures average level less than domestic 18%-20%, and product excellent in mechanical performance.
For reaching above-mentioned purpose, use technical scheme as follows:
A kind of resin mortar being applied to FRPM pipe, including resin and quartz sand, be by mass percentage:
Resin 11%-14%, quartz sand 86%-89%；
Wherein, the composition of resin is as follows:
Firming agent: methyl ethyl ketone peroxide 0.7%-0.9%；
Accelerator: cobalt iso-octoate/styrene 0.7%-0.9%；
Resin additive: polyacrylate 0.3-0.6%；
Remaining is adjacent benzene or isophthalic vinyl ester resin.
By such scheme, described accelerator is cobalt iso-octoate/cinnamic mixture, the most cinnamic mass percent
80%-90%.
By such scheme, described resin viscosity value should be less than 300mPa s.
By such scheme, described quartz sand is grating quartz sand, and each grating quartz sand accounts for the percentage ratio of quartz sand gross mass
For:
Less than 70 mesh: 32%-41%
1-3mm:40%-49%
3-5mm:12%-15%
5-8mm:4%-8%.
The preparation method of the above-mentioned resin mortar being applied to FRPM pipe, comprises the following steps:
1) quartz sand is cleaned, dry, by the particle diameter quartz sand mixing more than 1mm；
2) will join in resin less than the quartz sand of 70 mesh, after mix homogeneously, form resin-bonded mastic；
3) quartz sand of above-mentioned mixing is joined in resin-bonded mastic it is sufficiently mixed, fully vibrate and obtain being applied to FRPM pipe
Resin mortar.
The invention has the beneficial effects as follows:
The invention provides a kind of technical scheme with application and preparation in the high performance resin mortar of FRPM pipe, its resin demand
Less than the average level of domestic 18%-20%, resin mortar cost is effectively controlled.
The high performance resin mortar being applied to FRPM pipe of the present invention, its modulus of elasticity in static bending substantially beyond domestic at present
The average level of 6-8GPa.
Detailed description of the invention
In order to be more fully understood that the present invention, it is further elucidated with present disclosure below in conjunction with embodiment, but the present invention
Content is not limited to the following examples.
The resin mortar preparation process that the present invention is applied to FRPM pipe is as follows:
(1) preparation of quartz sand
The quartz sand of different-grain diameter is cleaned and goes the removal of impurity；Quartz sand through over cleaning is placed in thermostatic drying chamber
4～6 hours, cavity temperature was set to 120 DEG C, and after drying, quartz sand water content should be not more than 0.2%.After weighing drying by grating
Each particle diameter quartz sand；Will be greater than each particle diameter quartz sand mix homogeneously of 1mm, stand until quartz sand is cooled to room temperature.
(2) preparation of resin-bonded mastic
Weigh resin in proportion, be sequentially added into resin additive, accelerator, after stirring 2-4min, add firming agent；Holding is stirred
Mix, will be slowly added in resin less than the fine quartz sand of 70 mesh, after mix homogeneously, form resin-bonded mastic；For ensureing resin mortar
Smooth preparation, resin-bonded mastic must have certain mobility.In described resin-bonded mastic, resin is big with the ratio of fine quartz sand
It is about between 1:2.6 to 1:3.3.
(3) preparation of resin mortar
Joining mix in batches in resin-bonded mastic more than 1mm quartz sand, this process must whole process be kept stirring for；
Quartz sand should be sufficiently mixed with resin-bonded mastic, it is ensured that quartz sand particle is wrapped up by resin-bonded mastic；Resin mortar after mix homogeneously
Should fully vibrate, ensure that resin mortar is closely knit.
(4) maintenance
It is placed in left at room temperature maintenance, until resin mortar is fully cured；23 DEG C it are placed in, 48% humidity during conditions permit
In the environment of 4-5 days.
As a example by adjacent styryl ester resin makes resin mortar, each embodiment material fiting ratio and performance data such as table 1-
Shown in 4.
Table 1 each embodiment material fiting ratio
Table 2 each embodiment resin mortar compressive property test result (ambient temperature 5 DEG C)
Table 3 each embodiment resin mortar bending property test result (ambient temperature 5 DEG C)
Example 3 is tested under 25 DEG C of environment, and recording the average modulus of elasticity in static bending is 17.5GPa.
Table 4 each embodiment resin mortar density
From comparing result, different quartz sand graduations has following two aspects to the impact of resin mortar finished product:
(1) resin demand
As polynary grading of aggregates system, mixed its bulk density of grating quartz sand is closely related with porosity, heap
Between the grating quartz sand particle that long-pending density is high, porosity is less, and the resin-bonded mastic consumption being used as to fill is also less, and then resin
Consumption have also been obtained reduction.
(2) mechanical property
Inside the resin mortar that density is high more closely knit, defect is few, and therefore mechanical property is more excellent.
The present invention is not limited to above-mentioned specific embodiment in force, is also not necessarily limited to the application of FRPM pipe.It is being appropriately modified
Under can be applicable to the other field of the various applicable present invention.Therefore involved in without departing substantially from claims general concept
Under, the present invention is not limited to embodiment.
